Application filed February 21, 1912. Serial No. 679,148.

United States, residing at e county of York and State of a, have invented certain new and eve-merits in Dish-Vlfashing Maof my invention is to provide srwhich, While simple enough inderstood and operated by as, will subject the dishes to Lil wi th s necessity of employing a large amount oi. water. i

The invention will be understood from the r iscription hereinafter of the preferred einooc lent. thereof.

in inc.drawin gs-Figure lis a longitu dinal vertical sect-ion of an apparatus embodyi'ng my invention; Fig. 2 a plan view of the apparatus; lg. 3 an end elevation of the same; Fig. 4 a transverse vertical section through the ccnter of the apparatus. '5 a longitudinal vertical section through the spring device. I

Referring-retire drawings, A is a rectangular tank, in the present case having a length. greater than its width. The back a and ends a of this tank are most advantagcously formed (if-wood, while the bottom and front are advantageously made of one piece of sheet inetal, the upper front ed being rolled over as indicated at a -to form a suitable rim, The sheet metal forming the bottom is reflexed upward to form an inverted,truncated f-shaped central portion (4 extending the full length of the tank, whereby the interior of the tankis divided into two separate and independent waterholding compartments narrower at their bottoms than at their tops,'the central portion extending to any desired height up the interior of the tank so that the Water-h0lding compartments will have a depth sufficieht to hold the-water required to wash the ordinary dishes.

The tank A is arranged to receive a dishl'iolding basket B, which is shaped to conform to the interior of the tank A. the bottom of said basket being bent upward as indicated at 1b so as to conform to the upi'ard projecting portion a of the tank. This upward projecting portion 6 of the iich the following is a specifishing action of the water and.

ments, and the straight walls of the inverted if-shaped central. portion serve to support the dishes which may be placed on edge in the basket and lie against the said inclined SiCiQSSO as to permit a ready stacking of the dishes in the basket. The bask et- B is made of any suitable perforated material but particularly wire cloth, its upper edge being reinforced with a sheet metal rim as shown. At each end the basket rim is provided with handles as indicated at b and also, inside of the handles, with swinging hooks by which the basket is detachably connected to an operating mechanism as hereinafter described. This operating mechanism in the present example comprises a frame attached to the tank in such a manner as to be especially suitable as a handle or ball by which the tank may be carried. This frame or bail is formed of round iron rod and has two uprights, c, pivoted to the ends of the tank, one of said pivotal points being indicated at 0, Fig. 1. The uprights, c, are connected by a cross piece, 0 which bent upward at two points as indicated at 0 for a purpose hereinafter explained. in order to hold the bail or frame in its erect position, the ends of the uprights are provided with suitable holding devices such for example, as sliding bolts, (Z, arranged to engage socket pieces, d, secured'to the ends of the tank below the uprights. Each upright is provided vvith a slide, E, each of which carries an outward extending bearing, 6, through which extends, axially, a threaded clamping bolt, f, ha-vinga handle,

F, which is made of sufllcienfi size to be grasped by the entire hand for a purpose hereinafter explained. Each slide, also is provided with an inward extending arm which. at its lower surface carries a transversely arranged downward facing channel member or engaging device, 6', arranged'to engage the upper edge of the basket at the ends thereof. Each of these channel members is provided at the rear of the respective slide members with a notch as indicated at The inner face of each basket end is provided near its top, with two swinging latch devices, g, g, arranged to be swung upward to engage the upper surface of the respective channel devices, therear latch devices loo being arranged toi engage the respective notches, e at the rear of the slide devices.

A suitable counterbalancing mechanism is connectedto each=slide device, this mecha- I11SI11.1 1'1 the present example consisting of an adjustable spring .mechani-sm connected between the respective; slide device and the v corresponding .upwa d bent portion, .of'
